Now that I have one, I'm very confused about accessories for my iPhone. How can you tell if an accessory supports it? Without buying it and testing it out first, of course...
For example, I have a Belkin "Auto Kit for iPod w/ Dock Connector," which features the "Made for iPod" logo. It has a dock connector for charging and line-out audio, and it works great with my Photo iPod and 2G Nano. Will it work with my new iPhone? What about my various Docks, specifically either the "pre-remote" or "remote" Universal Dock?
